is the shado pan 522 trinket a big upgrade over the 476 relic for mutilate?

I know it sounds like a dumb question, but since agi is so much more valuble than everything else for us (the SP trinket giving up 900 base agi for hit), how big of an upgrade is it really? I know it's not an RPPM trinket, so is the ICD on that 8.8k agi proc low enough to make it worth spending 1.75k vp on replacing the relic of xuen?
